Those
involved in a management or decision‑making role for dispersion modeling
applications will be especially interested in the remainder of this section,
which provides an overview of the models, including their role in various
regulatory programs, a brief description of the range of available options,
and basic input data and computer hardware requirements needed to run the
models. From this information they should understand the basic capabilities
of the ISC models well enough to judge the suitability of the models for
particular applications. They may also want to review the brief tutorial
provided in Section 2 to learn about the nature and structure of the input
runstream file, in order to better be able to review the modeling results.

1.1.4 Programmers/Systems Analysts

Programmers and systems analysts, specifically those involved with installing
the ISC code on other computer systems or charged with maintaining the code,
should review the contents of Volume III. This will acquaint them with the
structure and organization of the computer code, give specific details on
compiling and linking the code for various situations, and explain in detail
the memory storage requirements and control of input and output (I/O). They
may also wish to review the remainder of this Introduction and the brief
tutorial in Section 2 of this volume in order to have a basic understanding of
the nature and overall capabilities of the models, and to understand the basic
input runstream file structure and organization.
